Ceci et al.'s (2006) findings remind us that tenure rarely serves its intended purpose. I argue that tenure often fails in part because many faculty members possess an insufficient appreciation for the heuristic value of controversy in science and other disciplines. Using two case examples from clinical/personality psychology, I show how controversial positions can draw sharp criticism while facilitating scientific progress.

Modern efforts to model cultural transmission have struggled to identify a unit of cultural transmission and particular transmission processes. Anthropologists of the early twentieth century discussed cultural traits as units of transmission equivalent to recipes (rules and ingredients) and identified integration as a signature process and effect of transmission.

Belief in souls is only one component of supernatural thinking in which individuals infer the presence of invisible mechanisms that explain events as paranormal rather than natural. We believe it is important to place greater emphasis on the prevalence of supernatural beliefs across other domains, if only to counter simplistic divisions between rationality and irrationality recently aligned with the contentious science/religion debate.

The Ceci et al. article is consistent with tenure being a necessary condition for controversial research. In the absence of tenure, as in the United Kingdom, professors have been fired and suspended for politically controversial issues. There are a variety of reasons why tenure does not ensure that professors will engage in controversial research, including career interests and the desire to be liked.

Understanding cultural evolution is one of the most challenging and indispensable scientific tasks for the survival of humankind on our planet. This task demands, besides an adoption of theories and models from biological evolution, theories for culture-specific processes as well. Language evolution and language acquisition offer interesting objects of study in this respect.

The dissociation of fluid cognitive functions from g is implicit in the Cattell-Horn-Carroll gF-gC theory. Nevertheless, Blair is right that fluid functions are extremely important. I suggest that the key mental operation assessed by measures of gF is the ability to sustain mental simulation while keeping the relevant representations decoupled from the actual world – an ability that underlies all hypothetical thinking.

Intraspecific aggression (IA), in service to dominance, has far deeper roots in animal behavior and human evolution than does predation. The reinforcing properties of such aggression are most likely to be a major source of human cruelty.

Bering's analysis is inadequate because it fails to consider past and present adult soul beliefs and the psychological functions they serve. We suggest that a valid folk psychology of souls must consider features of adult soul beliefs, the unique problem engendered by awareness of death, and terror management findings, in addition to cognitive inclinations toward dualistic and teleological thinking.

Various issues concerning the neural blackboard architectures for combinatorial structures are discussed and clarified. They range from issues related to neural dynamics, the structure of the architectures for language and vision, and alternative architectures, to linguistic issues concerning the language architecture. Particular attention is given to the nature of true combinatorial structures and the way in which information can be retrieved from them in a productive and systematic manner.

The target article by Ceci et al. provides some interesting results regarding how faculty might react to difficult social dilemmas, but it has little to say about tenure and its effect upon academic freedom. This comment discusses briefly what we know about tenure, and employment protection more generally, and why it may be in a university's best interest to hire tenured faculty. The comment concludes by pointing out that the results make a rather useful contribution regarding the difficulty of eliciting information on malfeasance in organizations, an area of enormous importance. For example, the results may help us understand why the government has introduced rewards for the reporting of fraud under the whistle-blowing provisions of the Federal Claims Act.

Bering's argument that human beings are endowed with a cognitive system dedicated to forming illusory representations of psychological immortality relies on the claim that children's beliefs in the afterlife are not the result of religious teaching. We suggest four reasons why this claim is unsatisfactory.

I propose a neuroscience and animat research-inspired model and a thought experiment to test the hypothesis of a developmental relation between fluid and crystallized intelligence. I propose that crystallized intelligence is the result of well-defined activities and structures, whereas fluid intelligence is the physiological catalytic adaptation mechanism responsible for coordinating and regulating the crystallized structures. We can design experiments to reproduce exemplified normal and anomalous phenomena, especially disorders, and study possible cognitive treatments.

van der Velde's & de Kamps's model encodes complex word-to-word relations in sentences but does not encode the hierarchical constituent structure of sentences, a fundamental property of most accounts of sentence structure. We summarize what is at stake and suggest two ways of incorporating constituency into the model.

Given the numerous parallels between the archaeological and paleontological records, it is not surprising to find a considerable fit between macroevolutionary approaches and methods used in biology – for example, cladistics and clade-diversity measures – and some of those that have long been used in archaeology – for example, seriation. Key, however, is recognizing that this methodological congruence is illusory in terms of how evolution has traditionally been viewed in biology and archaeology.

Fostering shame in societies may not curb violence, because shame is alienating. The person experiencing shame may not care enough about others to curb violent instincts. Furthermore, men may be less shame-prone than are women. Finally, if shame is too prevalent in a society, perpetrators may be reluctant to talk about their actions and motives, if indeed they know their own motives. We may be unable accurately to discover how perpetrators think about their own violence.

The study of culture from an evolutionary perspective has been slowed by resistance from some quarters of anthropology, a poor appreciation of the fidelity of cultural transmission, and misunderstandings about human intentionality.

Blair argues that fluid cognition is dissociable from general intelligence. We suggest that a more complete understanding of this dissociation requires development of specific process models of the mechanisms underlying fluid cognition. Recent evidence indicates that relational integration and inhibitory control, both dependent on prefrontal cortex, are key component processes in tasks that require fluid cognition.

I discuss weaknesses of the proposed model related to reinstantiation of encodings recorded by the hippocampal complex and to the inability of the model to explain complexity phenomena. An alternative model that also addresses the formation of hierarchical representations of sentences in working memory is outlined, and the ability of this model to account for complexity phenomena is briefly reviewed.

The fact that beliefs in the supernatural are useful to people who hold them does not necessarily mean that these beliefs confer an evolutionary advantage to those who hold them. An evolutionary explanation for any biological phenomenon must meet rigorous criteria, but the facts in this case, even when taken at their face value, fall well short of these criteria.

Does tenure serve its original purpose of promoting freedom of inquiry for academics in teaching and research? It seems not. Of concern is the finding that achieving tenure does not translate into a significant increase in exercise of freedom of inquiry either in teaching or research. Why? Promotion evaluation for associate professors by their senior colleagues has a continued inhibiting effect.
